Be 1t known that l, HERMAN F. BALL) of Bronxville, in the county of Westchester and 'State of New ,Yorin have invented :i certain new end useful Improvement in Drevvder- Pin Keepers7 of which improvement the :Eoilowing is a specification.

My invention relates to ineens for deteeli ably connecting railroad vehicles, particu lerly to appliances of the type set forth in, en application for Letters Patent tiled by me February 27, 1917, Ser. No. 151,213, and its object is to provide simple and effective Ineens for preventingl the occidente?. dieplacernent of dren/ber pins in service.

The improvement claimed is hereineiter fully set forth.

In the accompanying drawings: Figure Il is a vertical longitudinal central section through e. drewber appliance, illustre-ting an application of my invention; and, Fig. 9i, a vertical trensveree section on the line of Fig. l.

Under certeinstructnrel conditions, es in tanks, end'locomotives on which certain de -signs 0ic stoking mechanism are epplied,

drevvber pins cannot be inserted from above '.5

the drawbar, and it therefore becomes necessary to adopt some means 'to prevent tliem, when inserted from below, from accidentally dropping down and out of the drevvber..

and consequently inducing tlie separation of the locomotive end tender. lifly invention is designed to provide means, which will be readily applicable, et slight oost, in dreun bar constructions of any of the ordinary forms, for preventing this objectionable result.

My invention is herein exemplified as applied in connection with e locomotive and tender connection of the type of that of my application Ser. No. 151,213 aforesaid, there being a main draw bar, l, and an auxilieiv or safety drew bar, 10, which are couple respectively, to the locomotive by e pin, 2.,.

and to the tender bye. pin, 4. lt will, bowever, be obvious that it is similarly and equally applicable Where, as in ordinary Specification of Letters Appicetien tiled Mey 23, 5.91?.
